Abstract

The study of relaxation processes remains a challenge despite considerable theoretical and experimental efforts. In this chapter, we study such processes using a 1D Bose gas. The system is quenched by coherently splitting it into two parts. Matter-wave interferometry between the two parts is used to extract information about the dynamics. Measuring the full probability distributions of interference contrast reveals the prethermalization of the system to a non-thermal steady state, which can be characterized by an effective temperature.
